Friday8thJuly2011WMCConferenceCentre,WesternAustralianSchoolofMines,Kalgoorlie,WesternAustralia

Asset integrity is an important factor in the efficient operation of mining facilities; particularly when poor water quality (hypersaline conditions), frequent wet/dry cycling, high UV, high temperature and excessive debris collection on exposed surfaces are almost continuous factors promoting corrosion and durability issues to metallic, concrete and non-metallic structures on site. Consequently there are many strategies (simple and not so simple) being employed to ensure that the plant items are operated in a safe, efficient, durable and cost effective manner.

These strategies include the use of management systems as well as the physical processes of design,

fabrication and corrosion management methods. All of these strategies are important and are inter-related.

The Australasian Corrosion Association’s Mining Industry Technical Group is hosting a seminar to enhance corrosion awareness and to encourage dialogue on the various aspects of efficiently mitigating corrosion, with a special focus on the peculiar demands imposed by mining and mineral processing activities. The seminar will be of value to anyone (Maintenance and Operations related managers, operators, superintendents, supervisors etc.) involved in optimising mining operations to ensure that plant safety and availability is not compromised by corrosion.

There will be opportunity for delegates to participate in an open-floor forum as part of this seminar. Although hot topics generated at the seminar will be given priority, members planning to attend are encouraged to send topics and/or burning issues to be tabled for discussion by 1st July 2011 to [email protected]

Oil & Gas upstream and downstream operations are subject to corrosion degradation processes. From the initial drilling stage, where the first oxygen contamination is introduced to the producing formations, to the refining processes and the distribution of the light hydrocarbon products, corrosion is the common enemy. The risk and the likelihood of occurrence are the main factors to categorize the processes and prioritize the method and frequency of inspection, corrosion monitoring, and its control for the processing plant.

Oil & Gas industries have invested heavily in materials, technology, research and development to face the

increasing demand for oil and gas as the world’s main energy source and petrochemical feedstock. However, the investment in materials and personnel to improve corrosion monitoring and corrosion control is still very limited. Risk directed corrosion monitoring together with proactive corrosion control is the most cost effective and economical approach to win the battle against corrosion.

This Seminar aims to share with the audience selected topics to reflect the importance of setting inspection and corrosion management strategies for Oil & Gas operations.

There will be opportunity for delegates to participate in an open-floor forum as part of this seminar. Although hot topics generated at the seminar will be given priority, members planning to attend are encouraged to send topics and/or burning issues to be tabled for discussion by 1st July 2011 to [email protected]

Oil & Gas upstream and downstream operations are subject to corrosion degradation processes. From the initial drilling stage, where the first oxygen contamination is introduced to the producing formations, to the refining processes and the distribution of the light hydrocarbon products, corrosion is the common enemy. The risk and the likelihood of occurrence are the main factors to categorize the processes and prioritize the method and frequency of inspection, corrosion monitoring, and its control for the processing plant.

Oil & Gas industries have invested heavily in materials, technology, research and development to face the

increasing demand for oil and gas as the world’s main energy source and petrochemical feedstock. However, the investment in materials and personnel to improve corrosion monitoring and corrosion control is still very limited. Risk directed corrosion monitoring together with proactive corrosion control is the most cost effective and economical approach to win the battle against corrosion.

This Seminar aims to share with the audience selected topics to reflect the importance of setting inspection and corrosion management strategies for Oil & Gas operations.

Thethreemainfactorsinfluencingtheselectionofthecoatingtechnologytobeusedasthetankliningare;1)thetypeandconditionofthestoragevessel,2)thetypeandnatureofcargostoredand3)thecostsassociatedwithcoatinginstallationandthetankbeingout-of-service.Otherinfluencingfactorsofliningselectioninclude:thetankageanddesign,substratetypeandcondition,heatresistanceproperties,pitfillingcapability,corrosionprotectionandappropriatecoatingcertificationdocumentation.

Theavailabilityofdifferentrangesofmolecularweight,viscosityandfunctionalitywithintheepoxyresinsallowsforspecificdevelopmentofcoatingproperties.Theinclusionofepoxyphenolnovolacresinswithinthecoatingformulationincreasesthecrosslinkdensityofthecuredcoating,however,theyalsocanhaveanassociatedhigherviscosityandthereforeformulationofhighsolidsorsolventfreeliquidcoatingscanbedifficult.

Althoughtherearethreetypicaltypesofepoxyresins,thetechnologyofepoxycuringagentsisequallyimportanttodeveloparangeofcoatingswithpredictablechemicalandphysicalproperties,andinturnagreaterrangeofchemicalresistance2.

Epoxycuringagentsoriginallywereunmodifiedaliphaticaminessuchasdiethylenetriamine(DETA),triethylenetetraamine(TETA)andtetraethylenepentamine(TEPA).Theseaminecuredepoxiesprovidehighresistancetochemicalsandsolvents,howeverwithoutcorrectmodification,increasedbrittlenessofthecoatingcanoccur.

Corrosion of Fasteners in Treated Timbers – Experimental Findings from Field ExposuresAthreeyearfieldexposuretestonthecorrosionperformanceofvariousmetallicfastenersembeddedintotreatedtimbershasbeencompletedatBRANZ’ssiteinJudgefordnearWellington,NewZealand[12].AssessmentsconfirmedthatCuAzandACQtreatedtimbershaveanincreasedaggressivitytowardsmetalsincomparisonwithCCAtreatedtimbers.Theresultsafterthefirstyearofexposurearereportedhere.

IntroductionThecomponentsofanytimberstructureneedtobeheldtogetherusingfasteners.Hence,thecompatibilityofthetimberandthemetalwilllargelydeterminetheirmechanicalstabilityanddurability.Unfortunately,mosttimbersarenaturallycorrosivetowardssusceptiblemetalsduetothehydrolysisofacetylradicalstoaceticacidinthepresenceofmoisture[1-3].Water-bornepreservatives,commonlyappliedtoincreasetimber’sresistancetobiological,chemical,mechanical,photochemicalandthermalattack,canalsobeapotentialcorrosionhazard[4-5].

PastresearchbyBRANZhasfoundthatunderlaboratoryconditionstimbertreatmentsusingalkalinecopperquaternary(ACQ)andcopperazole(CuAz)preservativescausemorecorrosionofmildsteeland/orhotdipgalvanized(HDG)fastenersthancopperchromearsenate(CCA)treatments[6-8].However,thetestingconditionswerenotnecessarilyrepresentativeofatmosphericexposure.Therefore,BRANZhasundertakenlong-termfieldperformancetestingoftypicalfasteners(mildsteel,galvanizedsteelandstainlesssteelnailsandscrews).ThesefastenershavebeenembeddedintimberstreatedwithCCA(oxide),CuAz(CA-Bcontainingtebuconazole)andACQ(ACQ-Bcontainingdidecyldimethylammoniumchloride(DDAC)forH3.2andACQ-Ccontainingalkyldimethylbenzylammoniumchloride(ADBAC)forH4)toprovidereliablecorrosiondata.

MorphologicalObservationsAfteroneyearofexposureatBRANZ’ssitemildsteelfastenerssufferedrelativelyuniformcorrosiveattackacrossalloftheirsurfaces.However,fastenersincontactwithuntreatedandCCAtreatedtimberswereinverymuchbetterconditionthanthoseremovedfromACQandCuAztreatedtimbers(seeFigure1).Noobviouscorrosionfailureswereobservedontheheadofhotdipgalvanizednails.Insteadcorrosion,manifestingaswhiteand/orred-brownproducts,wasmainlylocalisedontheshaftarea.Coatingdegradationonthemechanicallyplatedscrewswasmoresevereandtheirspiralsectionsappearedtobethemostsusceptible.ScrewsinACQandCuAztreatedtimbers,

evenattheH3.2preservativelevel,wereextensivelyrustedontheirbodies(seeFigure2).SomescrewsembeddedintotheH4ACQtimberswere,infact,socorrodedthattheycouldnotbeextractedintact.Stainlesssteelfastenersperformedverywellinallcombinationsofpreservativetypeandhazardclass.Nosignsofcorrosionwereobservedontheirbodysections.Occasionallyverylimitediron-richrustcouldbeobservedonheads(seeFigure2).Thiswaslikelytheresultofpartialdamagetothepassivefilmand/orironcontaminationfromthehammerwhenthefastenerwasdrivenintothetimber.

CorrosionRatesConsistentwithmorphologicalfindings,corrosionratesoffastenersinCCA(H3.2&H4)treatedtimberswererelativelylowanddidnotdiffergreatlyfromthatofthoseembeddedinuntreatedtimbers.Incontrast,CuAzandACQtreatmentspromotedmarkedlyincreasedcorrosionrates(seeFigures3and4).Forexample,themildsteelnailshadacorrosionrateof6.63×10-2mm/yearinH4ACQtreatedtimber,whiletheequivalentcorrosionratesinH4CCAanduntreatedtimberswere1.87×10-2mm/yearand2.66×10-2mm/year,respectively.CorrosionaccelerationbyCuAzandACQtreatmentswasmoreobviousforthezinccoatedfasteners.Forinstance,thecorrosionratesofHDGnailsinH4CuAzandH4ACQtreatedtimberswere6.2and7.4timesgreater,respectively,thanthatofthenailsinH4CCA.Themasslossesofstainlesssteelfastenerswereextremelylimitedandverycloseto,orlowerthanthevalueoftheerrorassociatedwiththemeasurementtechnique.Hence,itwasimpossibletodeterminethepotentialinfluenceoftimberpreservationtreatmentontheirperformance.

Timber’sAggressivityvs.CopperRetentionThecorrelationbetweentheretainedcoppercontentinthetreatedtimberandtheexperimentally-measuredcorrosionrateoffastenerswasinvestigatedinthisstudy.Itcanbeseenthat:

1) ThecorrosionratesofmildsteelfastenersinH3&H4CCAtreatedtimbersareapproximatelyequaldespitetheretainedcopperinH4beingvirtuallydoublethatintheH3.2grade.

2) FastenersinCuAzandACQtreatedtimbershaveahighercorrosionratethanthoseinCCAtreatedtimber.Onaverage,CuAzandACQtreatedtimbershaveahighercoppercontentthanCCAtreatedtimber[9].ThecopperretentionratioofH4CCA,CuAzandACQis1:2.05:3.32whilethecorrosionrateratiosare1:2.07:3.55formildsteelnailand1:6.24:7.40forHDGnails.

3) AnincreaseofcopperretentioninCuAzand,particularly,inACQtreatedtimberswillincreasecorrosionrate.ThecoppercontentinH4ACQtreatedtimberisabout3timesashighasthecontentinH3ACQtreatedtimber,howeverthecorrosionrateinH4ACQtreatedtimberisonlyabout1.6timesashighastherateinH3ACQtreatedtimber.

Theseobservationsimplythatcopperretentionhasadegreeofcorrelationwithcorrosionrateandcopperionreductionislikelytobethecathodicreactionofthecorrosionprocess[10].However,itisunlikelytobetheonlymechanismactivelyresponsiblefortheenhancedcorrosionratesseen.Itmustberealisedthatthechemistriesofthesethreetreatmentsi.e.CCA,CuAzandACQ,arequite

PastresearchbyBRANZhasfoundthatunderlaboratoryconditionstimbertreatmentsusingalkalinecopperquaternary(ACQ)andcopperazole(CuAz)preservativescausemorecorrosionofmildsteeland/orhotdipgalvanized(HDG)fastenersthancopperchromearsenate(CCA)treatments[6-8].However,thetestingconditionswerenotnecessarilyrepresentativeofatmosphericexposure.Therefore,BRANZhasundertakenlong-termfieldperformancetestingoftypicalfasteners(mildsteel,galvanizedsteelandstainlesssteelnailsandscrews).ThesefastenershavebeenembeddedintimberstreatedwithCCA(oxide),CuAz(CA-Bcontainingtebuconazole)andACQ(ACQ-Bcontainingdidecyldimethylammoniumchloride(DDAC)forH3.2andACQ-Ccontainingalkyldimethylbenzylammoniumchloride(ADBAC)forH4)toprovidereliablecorrosiondata.

MorphologicalObservationsAfteroneyearofexposureatBRANZ’ssitemildsteelfastenerssufferedrelativelyuniformcorrosiveattackacrossalloftheirsurfaces.However,fastenersincontactwithuntreatedandCCAtreatedtimberswereinverymuchbetterconditionthanthoseremovedfromACQandCuAztreatedtimbers(seeFigure1).Noobviouscorrosionfailureswereobservedontheheadofhotdipgalvanizednails.Insteadcorrosion,manifestingaswhiteand/orred-brownproducts,wasmainlylocalisedontheshaftarea.Coatingdegradationonthemechanicallyplatedscrewswasmoresevereandtheirspiralsectionsappearedtobethemostsusceptible.ScrewsinACQandCuAztreatedtimbers,

evenattheH3.2preservativelevel,wereextensivelyrustedontheirbodies(seeFigure2).SomescrewsembeddedintotheH4ACQtimberswere,infact,socorrodedthattheycouldnotbeextractedintact.Stainlesssteelfastenersperformedverywellinallcombinationsofpreservativetypeandhazardclass.Nosignsofcorrosionwereobservedontheirbodysections.Occasionallyverylimitediron-richrustcouldbeobservedonheads(seeFigure2).Thiswaslikelytheresultofpartialdamagetothepassivefilmand/orironcontaminationfromthehammerwhenthefastenerwasdrivenintothetimber.

CorrosionRatesConsistentwithmorphologicalfindings,corrosionratesoffastenersinCCA(H3.2&H4)treatedtimberswererelativelylowanddidnotdiffergreatlyfromthatofthoseembeddedinuntreatedtimbers.Incontrast,CuAzandACQtreatmentspromotedmarkedlyincreasedcorrosionrates(seeFigures3and4).Forexample,themildsteelnailshadacorrosionrateof6.63×10-2mm/yearinH4ACQtreatedtimber,whiletheequivalentcorrosionratesinH4CCAanduntreatedtimberswere1.87×10-2mm/yearand2.66×10-2mm/year,respectively.CorrosionaccelerationbyCuAzandACQtreatmentswasmoreobviousforthezinccoatedfasteners.Forinstance,thecorrosionratesofHDGnailsinH4CuAzandH4ACQtreatedtimberswere6.2and7.4timesgreater,respectively,thanthatofthenailsinH4CCA.Themasslossesofstainlesssteelfastenerswereextremelylimitedandverycloseto,orlowerthanthevalueoftheerrorassociatedwiththemeasurementtechnique.Hence,itwasimpossibletodeterminethepotentialinfluenceoftimberpreservationtreatmentontheirperformance.

Timber’sAggressivityvs.CopperRetentionThecorrelationbetweentheretainedcoppercontentinthetreatedtimberandtheexperimentally-measuredcorrosionrateoffastenerswasinvestigatedinthisstudy.Itcanbeseenthat:

1) ThecorrosionratesofmildsteelfastenersinH3&H4CCAtreatedtimbersareapproximatelyequaldespitetheretainedcopperinH4beingvirtuallydoublethatintheH3.2grade.

2) FastenersinCuAzandACQtreatedtimbershaveahighercorrosionratethanthoseinCCAtreatedtimber.Onaverage,CuAzandACQtreatedtimbershaveahighercoppercontentthanCCAtreatedtimber[9].ThecopperretentionratioofH4CCA,CuAzandACQis1:2.05:3.32whilethecorrosionrateratiosare1:2.07:3.55formildsteelnailand1:6.24:7.40forHDGnails.

3) AnincreaseofcopperretentioninCuAzand,particularly,inACQtreatedtimberswillincreasecorrosionrate.ThecoppercontentinH4ACQtreatedtimberisabout3timesashighasthecontentinH3ACQtreatedtimber,howeverthecorrosionrateinH4ACQtreatedtimberisonlyabout1.6timesashighastherateinH3ACQtreatedtimber.

Theseobservationsimplythatcopperretentionhasadegreeofcorrelationwithcorrosionrateandcopperionreductionislikelytobethecathodicreactionofthecorrosionprocess[10].However,itisunlikelytobetheonlymechanismactivelyresponsiblefortheenhancedcorrosionratesseen.Itmustberealisedthatthechemistriesofthesethreetreatmentsi.e.CCA,CuAzandACQ,arequite
